Text in Class and Object Symbols
OM symbols have one or more text compartments, which should be
filled with a textual expression. While the OM Editor does not require
that symbol text compartments should contain text, it will perform a
syntactic check on text compartments as soon as they are changed and
deselected.
The syntax rules of OM diagrams are detailed in “Object Model Syntax” on page 1687.
Note:
The OM Editor does not enforce syntax correctness in OM class and
object symbols. This means that it is possible to use any conventions
you desire for the textual contents of symbols; however, some features offered by the OM Editor will not be available, notably the
Browse & Edit Class dialog.
Syntax checking on text in general is described in greater detail under
“Textual Syntax Checks” on page 1616.
